Antarctica is drier than Australia.
Only Antarctica is the drier continent than Australia. But Australia is the driest inhabited place.
Antarctica is sometimes considered the driest place on earth, so it is drier than all the other deserts of the world, except for the Atacama in South America where it is drier than most of the Antarctic land. There are few places in Antarctica, however, that are just as dry or maybe even drier than the Atacama.
Some parts of Antarctica are just as dry, if not drier, than then the Atacama. I call it a tie.

Antarctica. There is a desert drier than Australia which is the Atacama desert in Chile in South America but Antarctica can be much drier than the Atacama desert especially the Mc Murdo Dry Valleys
No. Antarctica is the size of USA and Mexico, combined. The coastal areas are generally warmer than the interior.
Antarctica covers 10% of the earth's surface. The interior of the continent is colder than at the beaches.
Antarctica is higher, drier, colder, windier, darker and icier than any other continent on earth.
Some call the interior of Antarctica the Polar Plateau. It is also the driest area of the continent -- humidity less than five percent, and is thus a desert.
Both Antarctica and the Atacama are drier that the Sahara Desert. Neither of which receives any appreciable precipitation.
